A fanfic could focus on a Pheromosa that has lost its memory. It tries to figure out where it belongs and what its purpose is. Along the way, it meets a group of friendly Pokemon who help it on its journey of self - discovery.
A simple idea could be a Pokemon Gold fanfiction where the trainer meets Clair during a Pokemon festival. They participate in a special Pokemon battle tournament together and form a strong friendship along the way.
Another possibility is that Pokemon exist in the Naruto world. Some ninja could have Pokemon as partners instead of traditional ninja animals. For example, Sasuke could have a Dark - type Pokemon like Umbreon that would match his cool and mysterious personality. And the Pokemon battles could be incorporated into the ninja battles, adding a new layer of strategy.
A great fanfic idea could be that Wally gets lost in an uncharted area of the Pokemon Ruby world. He has to rely on his wits and the help of his Pokemon to find his way back. During this time, he might discover a new type of Pokemon or a unique item that gives him an edge in battles later on.
One idea could be a story about Skyla's journey during her pregnancy. Maybe she discovers she's pregnant while on an important Pokemon delivery mission. She then has to balance her duties with taking care of herself and the unborn baby. It could show her friends in the Pokemon world coming together to support her.
One idea could be that Kurama, with his powerful demon abilities, has a unique bond with psychic - type Pokemon like Alakazam. Maybe he uses his chakra control skills to communicate with them in ways normal trainers can't. He could start his Pokemon journey in a region filled with mysterious forests, similar to the ones he knew in his original world, and form a team of Pokemon that complement his own strengths.
Maybe a story about a human who accidentally stumbles into the hidden realm of Legendary Pokemon. There, they form a friendship with a Legendary that is an outcast among its kind. Together, they try to change the perception of the outcast Legendary in its own community while also finding a way for the human to return home.
One idea could be Sonic and his friends accidentally end up in the Pokemon world. Sonic's speed could be a unique ability in Pokemon battles, like a super - fast attack or a way to quickly dodge enemy moves. For example, he could use his speed to outrun a powerful Pokemon's attack and then counter - attack. His friends like Tails could use his inventions to interact with the Pokemon technology, perhaps creating new Pokeballs or devices.
One idea could be a story where Lillie overcomes her shyness about wearing a swimsuit. Maybe she's at the beach with her Pokemon friends and they encourage her to have fun in the water. At first, she's hesitant, but as she sees how much her Pokemon are enjoying the beach, she gains the confidence to join them.
Maybe the human is a huge Pokemon fan in our world. One day, they touch a strange, glowing Pokeball they found. Suddenly, they start to transform into a Charizard. Their new form gives them the ability to fly and use fire - type moves. They then decide to use their new powers to protect the Pokemon in the forest from poachers.
